Letrozole - Year 2

It is so hard with a small child.  I know that was when my fitness went out of the window.  I don't know what your local community is like (or how old your child is) but see if there is a local Music & Movement type group that you can go to (usually 30 minutes of singing Play School style songs and dancing).  My local one closed down not long after my younger kids were old enough so I ended up starting my own - fantastic workout and the kids entertained.  (Do your own at home if that suits)  There may be other opportunities to exercise but it can be really difficult.  I suspect that given the conversations with your husband and SIL, you may be reluctant to take time for yourself, but it is important and believe me, the longer you go the harder it will be.  Parenting is a 2-way street in a couple and when there's another pressure (such as cancer) it may mean that the other person has to pick up the slack.  But I know that has difficulties if you're already struggling.  However, take it from me that the longer you go with a particular way, the harder it can be to change it.  Your health and fitness is important in the long run for your family as well as yourself.  If you are able to, get out for 30 minutes brisk walk first thing in the morning or in the afternoon while your child is otherwise occupied (and supervised).  A few laps of the pool while your child is in swimming lessons.  Get some small weights and chuck them in a cupboard in the lounge room (where your child can't get at them to hurt her/himself) and do some exercises in front of the telly.  I know it's hard and even harder with the family pressure but it is so important.  Take care.
